Step One

Look over all your items.  You should have a set of reins, a crown piece with two attached cheek pieces, and a cavesson with the browband attached to it.

Step Two

Remove the browband from the cavesson.  Unstrap the throatlatch, and remove the cheek pieces on the same side as the throatlatch buckle.

Step Three

Slide the browband through the open end of the crown piece and stop when you get to the spilt in the crown piece on the other side.

Step Four

Slide the other end of the browband through the open end of the crown piece but stop when you reach the split on that side of the crown piece.

 

Step Five

Reattach the cheek piece and throatlatch.

Step Six

Attach the ends of the cavesson to form a loop.  Take the longer strap and move it up the right side of the bridle, underneath the crown piece through the browband's loop and then down the left side, once more through the browband's loop.  Then attach the strap to the shorter cavesson strap on the left side.

Congratulations! 
Your Bridle is Completed! After you attach the reins, you're ready to go riding!
